You can expect warm hospitality from the staff and a very very clean place to stay at here. Jirayu is quick to respond and always ready to help. I have actually forgotten to return the room card which Jirayu readily agree for me to send it to him via post when I return home.
The front desk staff whose name I didn't get was extremely friendly and welcoming. They both speak good English so communication was easy. Yamyen hostel probably has the best balcony I've been to with a beautiful view of the airport where you can watch airplanes fly in all day long. With that said, the hostel is very close to the airport which is a great plus point as well (:
Would definitely make a return visit when we're back in Bangkok.
